Question

Balance the following equations:

$\mathrm{Mg}+{\mathrm{H}}_2{\mathrm{SO}}_4\to {\mathrm{MgSO}}_4+{\mathrm{H}}_2$

Answer 1

Step 1: Balanced chemical equations:

The chemical equations are said to be balanced only if the number of atoms and molecules are found to be the same on the reactant as well as the product side.

Step 2: Balancing the given equation

The given equation is:

$$\begin{gathered} \mathrm{Mg}+{\mathrm{H}}_2{\mathrm{SO}}_4\to {\mathrm{MgSO}}_4+{\mathrm{H}}_2 \\ \left(\mathrm{Sulphuric} \\ \mathrm{acid}\right)\left(\mathrm{Magnesium} \\ \mathrm{sulphate}\right)\left(\mathrm{Hydrogen}\right) \end{gathered}$$

• The count of magnesium (Mg) is 1 on both sides.
• The count of hydrogen (H) is 2 on both sides.
• The count of sulphur (S) is 1 on both sides.
• The count of oxygen (O) is 4 on both sides.

The reaction is already balanced as it contains an equal number of atoms for each element.
